PRINTING DEVICE.

Specification of Letters Patent.

Patented May 14, 1912.

To all whom it may concern:

Be it known that I, JOSEPH S. DUNCAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Printing Devices, of which the following is a specification.

This invention relates to that class of printing devices in which a printing plate is carried by a frame and which is adapted tobe stored in accordance with a card index system and run through an addresslng or other printing machine for taking an' impression therefrom.

The devices are used principally for printing addresses and are generally employed by those who send out many bills regularly to the same customers, such as gas companies, electric light companies and tel ephone companies. They are also largely used by publishers and other concerns that have largel mailing lists.

When a chan e in address occurs it has been customary eretofore to prepare a new printing plate and it is desirable to reduce the cost of thus maintaining the lists up to date by avoiding the necessity of replacing the entire plate. In the oase of a telephone company, for example, it may be that a telephone number will be permanently located ata certain address, and thus if the subscriber moves away from that address' it would be sufficient sim ly to change the name of the old subscri r for that of the new subscriberwithout changing the remainder of the printing' device, or the tele-- phone number may made the permanent feature of the print ng device and the address the detachable feature. This may occur in man other uses of these printing devices but t e example'y above noted will be suliicient to indicate the purpose of my invent-ion.

In my application` Serial No. 573,591, filed July 25, 1910 I have disclosed one way to obtain the results herein sought by providing a sectional printing late so that a part thereof can be replace and the other part continued in use.l But I have discoveredthat the same results can be obtained by making the permanent part of the printing form on the frame itself and the changeable part on `a removable plate adapted to be secured in the frame in proper relation to the permanent part of the form.

' arranged in l ing in the The object of my .invention is to reduce the expense of maintaining a system of printing devices of this general character by providing for the vrenewal of so much only of the printing device as is necessary when changes occur. And a further object of the invention is to provide the frame with Van integral and permanent printing form and with means for removably securing a printing plate on the frame in proper relation to the permanent printing form. And a still further object of the invention 1s to arrange the printing face of the type characters of the ermanent printing form on the frame in tllie same plane with or in a different plane from the printing characters on the plate when arranged in the frame.

In the accompanying drawings Figure 1 is a front view of my invention showing the permanent printing form on the frame in a lower plane than the rinting form on the plate. Fig. 2 is a simi ar view showing the permanent printing form in the same plane with the form on the plate. Fig. 3 s a sectional view on the line 3 3 of Fig. 1. Fig. 4 is a detail sectional view on the line 4-4 of Fig. 2. Fig. 5 is a transverse sectional view on the line 5-5 of Fig. 1.

Fig. 6 is a transverse sectional view on the line 6-6 of Fig. 2. Fig. 7 is a detail, view of the, printing plate.

The frame 8 1s provided at its ends with spacing fianges 9 of suitable character and at its top and bottom with beads 10 and 11. A card 12 is removably held in a card receiving space beneath the bead 10 and the lips 13 by en'd stops 14, or in anyother suitable manner.

The printing'plate 15, in the embodiment of the inventlon selected for illustration, has a complete address stamped in lrelief thereon and is held in a printing plate receiving space beneath the bead 11 and the lips 16 by the tongue 17 which is depressed sufficiently to engage an opening 18 inl the frame (Fig. 4). After the plate has been place in the frame the tongue can be readi y bent downward sufficiently to make pro er engagement with the ope'nrame, and it'can' likewise be readily pressed u Ward to ermit th'e plate to be removed rom the ramel whenever desired.

In the two embodiments of the invention illustrated in Figs. 1 and 2, the card and plate receiving spaces are separatedl from each other suiiciently to provide an intermediatey space for the permanent formwhich is stamped in relief directly in the frame. 'In Fig. 1 t-he form 19 is stamped up from the frame and its printing face lies in a plane below that of the form on the plate (Fig. 5.) However, the planes of the printing faces of the printing characters-of the trame plate and of the printing plate are disposed for making substantially simultaneous impressions. In Fig. 2 a panel 20 is pressed up on the frame and the permanent form 21 is stamped up from this panel so that the face of the permanent form. lies in the same plane with the face of the form on the plate. In the construct-ion of Fig. 2 the lips project from the upper edge of the panel and the lower edge of the panel forms a stop which is en aged by the upper edge of the plate 15. n the construction of Fig. 1 the lips 13 and 16 are suiiiciently removed from the permanent form 19 to be clear of the mechanism of the addressing machine and the frame is provided with a stopv 22 which co operates with the lip 16 to prevent upward movement of the plate. 1

Taking a printing device for use by a telephone company, for example, the telephone number and rate is shown in the drawings as the permanent form stamped from the frame and the subscribers address is provided on the plate so that the frame, which is a permanent part of the device, may be used indefinitely and the plate and card renewed as often as required. @bviously the particular forms of the frame and on the plate may be changed as desired without departing from the invention and in the eX.- ample shown the address might be made the permanent form on the enlarged panel and the telephone number the renewable form on the narrow plate.

My invention provides a simple method and meansl for reducing the cost of maintaining lists of names in the form of printing devices' especially Where frequent changes are required in the printing form.

What I claim and desire to secure by Letters Patent is: f

1. A printing device comprising a frame having an elevated panel stamped therein and provided with a ermanent printing form, means upon the rame at one side of the panel for holding a printing plate, and

means upon'the frame at the opposite side of Vthe panel for holding a card, substantially as described.

2. A printing device comprising a frame plate having permanent type characters stamped in an intermediate portion thereof,`

card-retaining means stamped up from the plate at one side of the permanent printing characters, printing plate retaining means stamped up from the plate at the. other side of the permanent printing characters, and a detachableprinting plate engaged with the printing plate retaining means, said detachable printing plate having printing characters stamped up therefrom, the planesv ing a card, substantially as described.
